WHEEL.

SPECIFICATION forming part of Letters'rtent No.v 700,215,4dated May 2o, 1902. Application filed April Z7, 1901.' lSerial No. 57.690. (No model.)

To a/ZZ whom, t may concern.- v

Be it known that I, JAMES MACPHAIL, a citizen ofthe United States, residing at Blue Island, in the county of Cook and Stateof Illinois, have invented a new and useful Construction of Vheels, of which the following is.A

n rangement, all as will be more fully hereinafter'set forth, as shown in the accompanying drawings, and finally pontedout in the ap- A` pended claims. I

Referring to the accompanying drawings and to the various views and reference-signs appearing thereon, Figure I is an edge View, partly in transverse section, of a wheel embodying the principles of my invention. Fig.-

2 is ay broken View, in side elevation, thereof. Figs. 3 and 4 are broken views, in transverse section, showing modified constructions ofwheels embraced Wit-hin the spirit and scope of my invention. Thel same partis designated by the same reference-sign Whereverl it occursthroughout the several views.

InY carrying out my invention I provide sheet-metal disks or plates which are mount-` kthus forming a sheet-metal wheel, thevinterlocking Y orengaging` oppositely projecting flanges formed at the peripheries of the sheets or disks forming or constituting the tread of the Wheel. By causing the iianges to engage and lock with each other so as to draw the outer edges or portions of the disks or sheets towardv each otherl into closer relation than the inner or central portions of said disks or sheets Ieffect a spreading apart of said sheets or disks centrallywhere said disks orplates are secured to'the hub, thus imposing a strain or tension upon the sheets or plates. In this manner I produce an exceedingly strong durable sheet-metal wheel, and Which is economical in construction.

Referring to the accompanying drawings,

vreference-sign A designates a shaft or aide,

and B the hub thereon.

C and D designate, respectively, thesheetmetal disks or plates centrally perforated to ifit over and to be attached centrally in: any suitable manner to the faces-or ends of the hub B, as clearly shown in Fig. I. Anysuit- `able or convenient means of attachment of the plates or disks to the hubniayfbe provided-as, for instance, rivet-bolts E`,'or otherWise. y

Each sheet or disk D is provided with a laterally-extendin g flangeat its outer periphery thereof, and the flanges on said disks or plates are arranged to project in-opposite directions with respect to each other and may be applied 4to each other or attached together in any suitable or convenient manner. I have shown various arrangements and means of attachment of said flanges. IFor instance, in Fig. l the flange F, formed onplate or disk C, is'iirst bentoutwardly and :laterally with respect to the plane of'said sheetror` disk, as indicated at G, 'and is then bentorefolded back'upon itself in the opposite direction, as clearly shown. The lange H of disk Orp-plate D is rst bent laterally and outwardly with respect to the plane of disk' D, asv indicated fat J, and is then doubled or folded'backnpon' itself and to extend in the opposite direction, as clearly shown, thus forming lateral flanges K L. The iianges F H may be applied to each other in any suitable manner and secured or fastened together. In the'v particular form shown in Figs. 1 and 2 the edge ofiiange F is arranged to be received Within thefold J of Ilange H, and the extreme edge of flange H is arranged to be folded over vtheloendor'late` eral flange Gr of sheet or plate C and-to engage underneath such bend or fold, as indi= cated at M, Fig. 1, thus eciently locking said flanges in engaging relation. In assembling the lateral flanges of the disks or plates C D the outer or peripheral portions of said disks or plates are drawn into closer relation with respect to each other or nearer together than the distance between the side faces of the hub B, as clearly shown, thus imposing a lateral strain or tension upon the plates or disks, which aids in strengthening the wheel and preventing lateral vibration of the disks or plates. In the form of construction shown in Fig. 3 the feature of the laterally-extending flanges K L is omitted and the outer edge of sheet or disk C' is merely turned inwardly toward plate or disk D', as indicated at F', and the outer peripheral edge of sheet o r plate D is folded over or laterally, as indicated at H', with the extreme edge thereof M', folded down over the corner or bend in plate or disk C', as clearly shown, the extreme edge of flange F' merely abutting against the surface of plate or disk D'. The construction shown in Fig. 4 is practically the same as that shown in Fig. 3, except that the lateral flange F2, formed at the outer orperipheral portion of plate or disk C2, terminates in a bend or flange N, over which plate or disk D2 extends or against which said plate or disk bears, the flange H2 of said plate or disk D2 being formed in the saine manner as flange H', (shown in Fig. 3,) the extreme edge of such flange M2, being folded down over the corner formed in plate or disk C2 by the bend of flange F2, formed therein.

From the foregoing description it will be seen that the tread portion of the wheel is formed of the lateral flanges, and the locking togetherof said flanges forms an eicient connection of the same together.

A wheel embodying the principles of construction above set forth is strong and durable, as well as light, and is exceedingly economical in manufacture, and such construction may be embodied in wheels for any desired purpose. I do not desire, therefore, to be limited in respect of the use or purpose to which the wheels are put; but I have found such construction particularly desirable in the manufacture of traction-wheels for road-engines, agricultural machines, and the like. It may be desirable in order to increase the traction of such wheels to attach to the tread the usual ribs P. These may be of the usual or any'well-known construction and may be mounted upon the tread portion of the wheel in any suitable or convenient manner-as, for instance, by rivet-bolts R, or otherwise.

Having now set forth the object and nature of my invention and a construction embodying the principles thereof, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent, is-

l. A wheel composed of sheet-metal disks or plates, each of said plates or disks being bent outwardly or away from each other at the outer peripheries thereof, said outwardlybent portions being bent or doubled back upon themselves to project in opposite directions, thereby forming laterally-extending flanges, the reversely-bent or doubled-back portions of one of said disks or plates having its edge turned over upon and under the laterally-extending flange of the other of said plates or disks, as and for the purpose set forth.

2. A wheel composed of sheet-metal disks or plates, each of said plates or disks being bent outwardly or away from each other at the outer peripheries thereof, said outwardlybent portions being bent or doubled back upon Vthemselves to project in opposite directions, thereby forming laterally-extending flanges, one of said` flanges to constitute the tread portion of the wheel, said flanges beingr arranged to engage and lock with each other,

as and for the purpose set forth.

In witness whereof I have hereunto set my hand, this 24th day of April, 1901, in the presence of the subscribing witnesses.

JAMES MACPHAIL.
